Does someone need to give Justin Bieber a curfew? The 19-year-old singer was “lazy,” “sluggish,” and “bored” at his concert in Newark, NJ, on Wednesday night, according to one review, after partying until 6 am the night before in New York City.

Justin “seemed to be lip synching and his sluggish, lazy dancing didn’t match the oomph of the beats,” Mesfin Fekadou of the Associated Presswrote after the show.

The critic continued, “Bieber phoned in a good amount during his show; at some moments, he even appeared bored. He was clocking in — another day, another sold-out concert.”

Late nights out have become the norm for Justin in recent weeks: He’s been spotted partying it up in Boston, Cleveland, Indianapolis and other cities.

Even party girl Miley Cyrus thinks he might want to slow down his partying pace: She recently said, “I told Justin to take a bit of time out … He’s still stupid though. But everyone does dumb stuff when they are messed up, and he’s done dumb stuff.”
